If you photograph outdoors as I often do, you’re going to realize that great big blue sky of ours has an impact on our photographs. When I look at portfolios, more than 75% of the time I see outdoor images with a hideous blue color cast. This is subtle in some cases and not so subtle in others.

This is VERY easy to fix in post with the Hue Saturation command. Hue/Saturation.

Hue/Saturation is one of the core adjustments available in Photoshop. This command applies changes to every selected pixel’s color value, according to its nearest HSB equivalent. In modern Photoshop versions, changes can be limited to a specific range of hues.

Using Photoshop, create a duplicate layer, then hit the key combination of Command-U on a Mac or Ctrl-U on a PC. This calls up the Hue/Saturation dialog box.

Select the BLUE channel and reduce it to about 70%. (You may also need to do this on the Cyan channel.) On the duplicate layer, erase any areas where you want to leave the blue color. You can also adjust the opacity of the NOBLUE layer. You can also do this in reverse and create a mask to paint in the NOBLUE. There are several ways to do it. What matters is that you do it.

In the photo above, you can see the blue cast in the eagle’s wing on the original photo and see it’s been removed in the corrected photo. Subtle but meaningful. Give it a try.

NOTE: We’re not saying this is the ONLY way to achieve this result in Photoshop – it’s just A way to do it. Your mileage may vary. We hope you find it helpful.
